UMBRELLA Filed Dec. ll, 1930 /rak 1 W Patented Oct. 20, 1931 uN rD S TS PATENT oFFlCE nMrLE'Co-RNICT, or 1 3118, FRANCE TMBRELLA' towards the opposite end of the stem the structure constituted by the nut and the ribs, thus causing the end of the ribs to enter a cup niounted on the handle When the uinbrella is closed.

The tension of the above lnentioned resilient member automatically holds the umbrella in this position, Whilst in the existing devices, hich are usually provided With a cup sliding on the handle, the ribs can easily slip out of the said cup; moreover, the frequent sliding of the cup rapdly damages this handle. Finally, the fixed cup is quite independent of the size and shape of the handle, Whilst the sliding cup Was necessarily 2.3 related to this size and shape, Which practi- Cally rendered it unapplicable to ladies umbrellas.

Another advantage resulting froln the resilient mounting of the nut Carrying the ribs, consists in that the covering fabrc is not liable to be subjected to eXcessive stresses When the umbrella is opened to its full extent, Which frequently happens With the ordinary rigd mounting When the size of this fabric is slightly nsufiicient: i

On the other hand, oW ng to the fact that the cup is fiXed, the assemblage of the unibrella on its stem as Well asthe securing in position of the arm-knot Or arm-strap include appreciable siinplifications consisting v in that the arm-knot Or arm-strap s secured to the stein by a ring to Which it is connected, and Which may either be previously assembled With the cup by beading or otherwise, or

4 held in place by clamping between a shoulder of the said stem and the base of the handle mounted on thelatter. Thering is therefore firmly held Without having to employ any of the standard assembling devices.

The accompanying drawings illustrate, by

No. 501,631, and in France June 18, 1930.- j

Way' of example, an umbrella according to the invention, the fabric being removed. a A

Fig. 1 is an elevation With axial sections according to the axis. l l i,

Fig. 2 is' a cross section On line 'II-II of Fig. 1.' i J Forsimplification, the inner branches, and themovable nut servingto move the ribs through the medium of the said branches have not been shown, as these usualnmembers pre-sent no partieularitvjn i 'The nut 1, On Which'the ribs 2 are attached by awire 3 in the usua-lmanner, is slidably mounted on ashort sleeve 4 secured about a tenon 5 provided at the end of theLstem. r e

:Aspring 6 is interposed between the sleeve 4: and the nut* 1: and bears, On the one hand, On a flange 7 carriedby the endof the sleeve 4 and, on the other hand,*on aledge la integfi ral With the nut. This spring, Which is a compression spring, constantly returns the nut and ribs towards the opposite end of the stein; their displaceinent is limited by, the shoulder 8 Ofthe stem. v g

On the other hand, a cup 9 is mounted on a reduced portion of theihandle, so that it can fitover ,or cover the tips of the ribs.iThis Cupis held, 'or instance, by a cap 10 secured On the reduced end of the handle, The relax v tive arrangement of these Various members is such that in closed position, the spring 6 pushes the ribs 2, so that the ends of the latter enter the cup 9 and are held therein.

Thenut l is rigid With the socket 12 Which covers the spring 6 and the'end of the stein v and Which Can only longitdinally slide relatively tothe latter, the relativerotation of these parts being prevented by ribs 13 of the socket 12 which-rextendnin notches of the flange7. a

A cap or cover 15 secured to'the socket 12 protects and coneeals the device thus ars ranged. i e n i This guide device serving to'prevent the ribs' from rotating' about the ste1n,jis shown by Way ofexample onlyandcould 'be replaced by any other suitable device.g l i e The umbrella being closed, it sufices, for Opening' it, to eXert a slightpull on the handle and on the ribs, so asto* compress the spring;-

and to release the end of the latter. The same Operation effected when shutting the umbrella, allows of bringing the ribs against the stein; the spring expands when the handle is no longer pulled upon and the cup 9 covers and holds the ribs.

On the Other hand,' the'arm-knot Or armstrap 16 of the: umbrella is mounted in the following manner: this arm-strap is sccured to a Washer 17, for instance by means of rings 18, 19 carried by these two' parts: The washer 17 can be held on the handle between the shoulder of the latter and the bottom of the cup 9.

In case the handle is removable, its withdrawal allows of instantane'ously: removing r the washer'l7' and the arm-strap as well as the' cup'9.

It is to be understood tha t the inven'tion *is not limited to the form o'l' construction above described solely by way of example and that,- without *departing from :thesaid invention, the shape andarrangcment of these Constituent part-s might *be* modifiedin any suitable 'mann'cm the nut 1 and its returning device might be mounted on :the stein -in any Other a manner 'than that illustrated', the washer '17 and 'cup-9 inightbe'left'independentas shown,

01' theymight be assembled for 'instance by beading,^or'they 'might again be connected in one piece by pressing, 'and the handlemight be'off anyshapeand mounted on the stein by' other method *than'th-ose shown. Fn-

ally; the cup= might be 'provided in' the base itself f'the handle; it 'can be given' apolygi onal sha'pe; having for instance' as 'many v apices'- as' there 'are ribs; etc.
